			* procinfo renamed to current_procinfo
  * procinfo will now be stored in current_module so it can be
    cleaned up properly
  * gen_main_procsym changed to create_main_proc and release_main_proc
    to also generate a tprocinfo structure
  * fixed unit implicit initfinal

 | |
|     * aktprocdef renamed to current_procdef
 | |
|     * procinfo renamed to current_procinfo
 | |
|     * procinfo will now be stored in current_module so it can be
 | |
|       cleaned up properly
 | |
|     * gen_main_procsym changed to create_main_proc and release_main_proc
 | |
|       to also generate a tprocinfo structure
 | |
|     * fixed unit implicit initfinal
 | |
| 
 | |
|   Revision 1.37  2003/04/27 07:29:50  peter
 | |
|     * current_procdef cleanup, current_procdef is now always nil when parsing
 | |
|       a new procdef declaration
 | |
|     * aktprocsym removed
 | |
|     * lexlevel removed, use symtable.symtablelevel instead
 | |
|     * implicit init/final code uses the normal genentry/genexit
 | |
|     * funcret state checking updated for new funcret handling
 | |
| 
 | |
|   Revision 1.36  2003/04/22 23:50:22  peter
 | |
|     * firstpass uses expectloc
 | |
|     * checks if there are differences between the expectloc and
 | |
|       location.loc from secondpass in EXTDEBUG
 | |
| 
 | |
|   Revision 1.35  2003/03/08 08:59:07  daniel
 | |
|     + $define newra will enable new register allocator
 | |
|     + getregisterint will return imaginary registers with $newra
 | |
|     + -sr switch added, will skip register allocation so you can see
 | |
|       the direct output of the code generator before register allocation
 | |
| 
 | |
|   Revision 1.34  2002/10/16 19:01:43  peter
 | |
|     + $IMPLICITEXCEPTIONS switch to turn on/off generation of the
 | |
|       implicit exception frames for procedures with initialized variables
 | |
|       and for constructors. The default is on for compatibility
 | |
| 
 | |
|   Revision 1.33  2002/10/14 19:43:41  peter
 | |
|     * threading switch, defines the symbol FPC_THREADING
 | |
| 
 | |
|   Revision 1.32  2002/10/05 12:43:24  carl
 | |
|     * fixes for Delphi 6 compilation
 | |
|      (warning : Some features do not work under Delphi)
 | |
| 
 | |
|   Revision 1.31  2002/08/19 19:36:42  peter
 | |
|     * More fixes for cross unit inlining, all tnodes are now implemented
 | |
|     * Moved pocall_internconst to po_internconst because it is not a
 | |
|       calling type at all and it conflicted when inlining of these small
 | |
|       functions was requested
 | |
| 
 | |
|   Revision 1.30  2002/08/12 15:08:39  carl
 | |
|     + stab register indexes for powerpc (moved from gdb to cpubase)
 | |
|     + tprocessor enumeration moved to cpuinfo
 | |
|     + linker in target_info is now a class
 | |
|     * many many updates for m68k (will soon start to compile)
 | |
|     - removed some ifdef or correct them for correct cpu
 | |
| 
 | |
|   Revision 1.29  2002/08/06 20:55:20  florian
 | |
|     * first part of ppc calling conventions fix
 | |
| 
 | |
|   Revision 1.28  2002/07/04 20:43:00  florian
 | |
|     * first x86-64 patches
 | |
| 
 | |
|   Revision 1.27  2002/07/01 18:46:22  peter
 | |
|     * internal linker
 | |
|     * reorganized aasm layer
 | |
| 
 | |
|   Revision 1.26  2002/05/18 13:34:08  peter
 | |
|     * readded missing revisions
 | |
| 
 | |
|   Revision 1.25  2002/05/16 19:46:36  carl
 | |
|   + defines.inc -> fpcdefs.inc to avoid conflicts if compiling by hand
 | |
|   + try to fix temp allocation (still in ifdef)
 | |
|   + generic constructor calls
 | |
|   + start of tassembler / tmodulebase class cleanup
 | |
| 
 | |
|   Revision 1.23  2002/05/12 16:53:05  peter
 | |
|     * moved entry and exitcode to ncgutil and cgobj
 | |
|     * foreach gets extra argument for passing local data to the
 | |
|       iterator function
 | |
|     * -CR checks also class typecasts at runtime by changing them
 | |
|       into as
 | |
|     * fixed compiler to cycle with the -CR option
 | |
|     * fixed stabs with elf writer, finally the global variables can
 | |
|       be watched
 | |
|     * removed a lot of routines from cga unit and replaced them by
 | |
|       calls to cgobj
 | |
|     * u32bit-s32bit updates for and,or,xor nodes. When one element is
 | |
|       u32bit then the other is typecasted also to u32bit without giving
 | |
|       a rangecheck warning/error.
 | |
|     * fixed pascal calling method with reversing also the high tree in
 | |
|       the parast, detected by tcalcst3 test
 | |
| 
 | |
|   Revision 1.22  2002/04/21 19:02:03  peter
 | |
|     * removed newn and disposen nodes, the code is now directly
 | |
|       inlined from pexpr
 | |
|     * -an option that will write the secondpass nodes to the .s file, this
 | |
|       requires EXTDEBUG define to actually write the info
 | |
|     * fixed various internal errors and crashes due recent code changes
 | |
| 
 | |
|   Revision 1.21  2002/03/24 19:05:59  carl
 | |
|   + patch for SPARC from Mazen NEIFER
 | |
| 
 | |
|   Revision 1.20  2002/01/24 18:25:48  peter
 | |
|    * implicit result variable generation for assembler routines
 | |
|    * removed m_tp modeswitch, use m_tp7 or not(m_fpc) instead
 | |
| 
 | |
